lamincc are straight, not valanced*. In specimens of from four to 

 five inches, a fourth hmiina makes its appearance in the basal centre 

 of the third lamina. The other lamina) continue to grow in their 

 cii'cumference, and their edges now become undulated and slightly 

 valanced. Cuvicr and "Valenciennes have examined still larger speci- 

 mens ; the figure given by them was taken from a specimen six or 

 seven inches long, and shows the superbranchial organ composed of 

 six laminae. The connexion of this organ with the gill-apparatus 

 has been examined and fully described by Peters t. 



It may be supposed that, as in other fishes, the difference in the 

 size of individuals does not always coincide with a corresponding 

 difference in age ; and if, for instance, there should occur specimens 

 four inches in length with the superbranchial organ as complicated 

 as it is generally found to be in the larger ones, it would not form 

 an objection to the facts stated.

The height of the body is contained three times or three times and 

 three-fom-ths in the total length, the length of the head three times 

 and a half or four times. The prteorbital and the opercles are 

 denticulated, the teeth of the angle of the operculum and sub- 

 operculum being more or less produced. Greyish-olive : immature 

 specimens with two brown streaks on the side of the head, and with 

 a black spot at the base of the caudal fin. Two spines of the oper- 

 culum form a notch, the membrane of which is black.
